wow, did you but it from a retail store or online? Steam or ebay? There are a few risky places that I've never been to comfortable buying from. As far as products that activate on steam or online in general, Ive always been antsy about buying from other retailers.

Hopefully you can get that straightened out. No matter how much you actually spent it still is bad to be in that spot.
Good Luck.

Bought it at a big electronic store here in sweden. (www.elgiganten.se)
I know that they are trust worthy.

Btw, I haven't gotten the "CD-key is in use" message since I contacted Activision.
But I think it was the other dude who got another key.
I can't even IMAGINE Activision helping a customer, how sad...
